I lost one of my keys. Is it possible to erase all keys from memory and readd the keys I have? I have a master key.

My boosted IS came with one master key i need to get another so me thinks i'll try this...

My IS came with a master key and a valet key, so I want to get a second master key off eBay and try this but I have one question.

What is the difference between "key programming (starter chip)" and "remote programming"? Is there a chip in both types of keys that allows it to turn over the motor, then the remote lock/unlock is separate?

This doesnt have anything to do with keys but it does have to do with the key/ecu relationship.

Is there any other place other than lexus that can clear the key code off the ecu? I am trying to see if I can use another ecu with my car and not have to drive the car to a dealer to get it looked at.

So if I get a new master key, do I need to do both procedures?

shinergloc · 01-15-2009, 10:45 AM

yes if you plan on getting a master remote key, you'll have to do both procedures... the key programming and the remote programming. it took me 1 try to do the key programming and like 5 tries to do the remote programming. i read the instructions wrong, but when i figured out what i was doing wrong, it took only 1 try.

as for the clearing the key code for the ecu... you can do a forums search. there is a sequence you can input to clear it, but that person said it was a huge MISTAKE. dont know why, but just FYI

do u know how to program the locks so that all 4 doors unlock with one (not two) button pushes on the remote?

Bumping an nold thread instead of opening a new one...

I tried the "Remote Programming". No luck. I can't get passed step 7. It will not go into programming mode. Questions are:
Step 1: Do I close and lock the doors when I am inside the car with the Electric lock or Do I stand outside and lock it with the key? Do I unlock it inside with the electric lock or do I stand out side and unlock it with the key?
Step 2: No issues here. Simply put in and take out immediately.
Step 3: How quickly do I press the lock/unlock? 1 sec intervals? 5 secs?
Step 4: Ok
Step 5: See step 3's question
Step 6: Do I just insert key, put it in the "On" position and immedialtely turn off and remove?

Thanks!

You do it inside the car with the doors shut. about 1 second intervals.
